I think that’s a simplistic view of it. As far as I’ve followed along, Russia has been having droughts and mega fires which tend to be incompatible with high crop yields.
Talking about megafires, Chernobyl’s surroundings are sitting under dry leaves, because bacteria and insects have defects and don’t decompose them properly.
Well I believe the droughts and wildfires are not really occurring in Siberia, which is the area I think some are speculating will become a breadbasket.
Living around Seattle, I disagree, lately there have been articles just about every year about wildfires or drought in Siberia, and many about those fires causing smoky skies in Seattle.
Siberia has awful soil that doesn't have nearly the nutrients necessary to support large scale agriculture even if the temperature shifts. You could fix that, but it would take the same amount of time as trying to fix climate change (at least on a big enough scale).
